Data Sheet
Valve station
Type ICF SS 20 and ICF SS 25
A complete range of modern, €exible stainless steel components for Industrial refrigeration
Based on advanced technology the ICF SS valve station incorporates several functions in one housing, which can replace a series of conventional mechanical, electro-mechanical and electronically operated valves.
This valve station not only provides a number of advantages in the design phase of a refrigeration plant but also in the installation, service and maintenance.
The ICF SS valve stations are designed for low and high pressure refrigerants and can be used in pumped liquid lines, liquid injection lines and hot gas lines.
Supplied as a complete assembly, it is fully tested at high pressure and its functions are tested under factory controlled conditions.
One code number equals one application solution.

Valve station, Type ICF SS 20 and ICF SS 25
Features
•Designed for industrial refrigeration applications for a maximum working pressure of 52 bar / 754 psig
•Applicable to HCFC, non €ammable HFC, R717 (Ammonia) and R744 (CO2). The use of ICF SS valve stations with €ammable hydrocarbons is not recommended
•Direct weld connections (No leaks through €anges)
•Stainless steel valve housing and function modules
•Low weight and compact design
•V-port regulating cones on the control modules ensure optimum regulating accuracy particularly at part load
•Modular Concept
◦Each housing is available with butt-weld DIN connections in several sizes. Valve service is performed by replacing the function module
•Side ports for the connection of pressure gauges, transmitters, sight glasses, service valve etc
•UL approved

Refrigerants
Applicable to HCFC, non €ammable HFC, R717 (Ammonia) and R744 (CO2). The use of ICF SS valve stations with €ammable hydrocarbons is not recommended.
New refrigerants
Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.
When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specific refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.
